Experience for units already lost
Día de Muertos is a Commerce Age Mexican Cathedral technology; Peru can research the identical Diablada after its Revolution route provides Cathedral access. Research takes 30 seconds. Completion grants five experience for every unit the player has lost so far, including herdable animals. The reward is calculated from the existing loss count, so it is a one-time experience payout rather than a bonus to future deaths.
Choose the research timing
The experience return grows with the number of units lost, making timing important. Researching early provides less experience, while waiting can delay Home City shipment progress and consumes a Cathedral research window. Compare the expected payout with the 30-second delay and the value of other Cathedral options. The Mexican and Peruvian names differ, but the recorded effect is identical.
